Save email right to Salesforce like you can do with the Outlook Connector already. Not sure if it has 100% of this functionality such as Attachment saves.

Generate Google Docs, Spreadsheets and Presentations right from Salesforce and have them linked to your records. The Google Docs side will allow for strong collaboration and the linkage to Salesforce will ensure that everyone is working off the right document. I was unable to tell via the video if you can do Mail Merge to Google Docs like you can with MS Word.

Google Chat is embedded in the Salesforce sidebar allowing you to chat with people right from within Salesforce

Scott, thanks for the mention. We (Appirio) are incredibly excited about what has come and the potential for the future. These offerings start to bridge the gap between the tools that businesses need to run and the tools that people use to work. What’s remarkable is the role that partners can play by building on these platforms– Appirio launched an expanded services practice and 4 new (mostly free) extensions to Salesforce for Google Apps, allowing users to synchronize calendars, collaborate on marketing campaigns, find and embed documents, and create and share customized CRM dashboards (http://appirio.com/products/index.php). And this is just the beginning– solutions for business, meet solutions for businesspeople!
